Ok I had some time to investigate what I discovered (in comment 68). Still not sure if it's the cause of this bug but I am now able to reliably reproduce a serious similar bug:
1. launch users-admin 2. create a test1 user 3. create a test2 user (with admin rights) 4. create a test3 user 5. delete the test1 user 6. delete the test3 user Here you go, test2 is no longer in the admin groups. I opened a bug upstream where I put a detailed explanation: http://bugzilla.gnome.org/show_bug.cgi?id=489187 -- Adding a user to a group modifies other users' groups and passwords https://bugs.launchpad.net/bugs/26338 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
